The Oseco PLR is a precision, low-pressure, non-fragmenting, reverse-buckling rupture disc. It offers extremely low burst pressures in an all-metal design. The armored construction of the PLR protects the disc from damage that affects the performance of other low-pressure rupture discs.
Standard disc materials are 316 Stainless Steel, Iconel®-600, Monel®-400, and Nickel-200/201. For additional corrosion protection, a PFA fluoropolymer liner is available on the process side. The top portion/retainer ring on the atmospheric side of the PLR is always 316 Stainless Steel.
The PLR is excellent for use in protecting and isolating safety relief valves. Due to the large opening characteristics, in some sizes an extended outlet holder may be required when installed directly under an SRV.
